Top 5 Benefits of a Cloud Email Security Service

Email security is a major component of any company’s defenses against the myriad of threats originating from the Internet. Traditionally, a variety of software and appliances have been used to combat against the ever-evolving threats, however, more and more companies are now turning to the cloud to assist with their defense.

Below are the top 5 benefits that a cloud based email security service can bring to companies.

1. Service Level Agreements (SLA)

All cloud email security service providers (at least the good, reputable ones), should offer clearly defined SLAs in their customer contracts. This is essentially what the customer is paying for, the appropriate “level of service” for the email security solution.

2. Threats Detection and Prevention

On-premise solutions would not be able to offer any SLAs relating to threats, such as the 100% email virus catch rate, or 99% spam catch rate.

3. Availability and Resiliency

Cloud solutions should be able to absorb any DDOS attacks, or spikes in traffic, and still permit normal mail traffic to be processed and flow through to reach the company’s email system.

When using a cloud solution, during any disruptions to the company’s network, such as to the internet connection, firewall, etc., the mails would just queue up in the cloud data center, there would not be any lost mail.

It becomes the responsibility of the cloud service provider to ensure that the service is available, look out for the relevant SLAs in the contract.

4. Bandwidth Savings

As the majority of unwanted mails such as virus mails and spam mails are being filtered in the cloud before it reaches the company’s network, there would be savings in the Internet bandwidth.

5. Cost Containment

As cloud email security is a service, without any necessary hardware, the expense for this should be able to be considered operating expenditure rather than capital expenditure.

Cloud solution would have a single predictable cost, compares to on-premise solutions, where you would need to factor in multiple tangible (hardware replacement, power, storage, cooling, redundancy, etc.) and intangible costs (staffing, manpower, effort, cost of equipment failure, etc.).
